Abstract
A method for monitoring seismic and microseismic activity in a subsurface includes positioning one or more seismic sensors at a wellsite. The method also includes positioning a plurality of non-seismic sensors at the wellsite. The method also includes measuring seismic data using the one or more seismic sensors. The method also includes measuring non-seismic data using the non-seismic sensors. The method also includes synchronizing the seismic data and the non-seismic data to produce synchronized data. The method also includes mapping seismic hypocenters in the subsurface based on the synchronized data.
